Hooking/Scraping .NET application

I would like to create a trading bot for Magic Online. If it's a concern, doing that would not violate the terms of use, and several vendors for such a bot exist. I initially started out with the DLL injection/API hooking path, but that doesn't work as it doesn't seem to call any of the standard GDI func开发者_JAVA技巧tions. My code works fine on Notepad, but does nothing on MTGO_NET. Same result with third party hooking libraries.

I then "gave up", and decided to try to use OCR. However, this weird thing happens when I try to do a screenshot of the client window: I only get the game's splash screen, no matter what the client is actually displaying. The main window device context is always the splash screen. I am guessing the client uses a separate device context to actually render the game, and I have to somehow figure out what that DC is. Does anyone have experience encountering this issue? I would gladly take any advice regarding either hooking .NET applications or how to take a screenshot.

I am testing all this on Windows Vista Ultimate 64 bit. I haven't tested this on a 32 bit installation, but I hope that isn't an issue.

I suggest you look here: http://www.mtgnews.com/showthread.php?t=191879

Which provides a link to source code for a 'working' bot.
